Give the Humminbird 737 a look. I used one for 2years sold for 35.00 less than what I paid for it. When I upgraded my 2nd unit to color also. I was more than pleased with it and it convinced me into investing in the more expensive HB units.
It comes standard with the Quadbeam plus. A great tool for finding structure and fish.
Only drawback is it is B/W but I really liked mine.
